#### Answer

$q=-2+p+r$

#### Work Step by Step

$\bf{\text{Solution Outline:}}$ To solve the given equation, $p-q+r=2$ for $q ,$ use the properties of equality to isolate the variable. $\bf{\text{Solution Details:}}$ Using the properties of equality to isolate the variable, the equation above is equivalent to \begin{array}{l}\require{cancel} p-q+r=2 \\\\ -q=2-p-r \\\\ -1(-q)=-1(2-p-r) \\\\ q=-2+p+r .\end{array}
